Question

if A and B are the zeros of the quadratic polynomial p(x)=4x^2-5x-1 ,find the value of A^2B+AB^2​

Answer 1

d^2 = b^2-4ac

d^2 = 25-4×4×(-1)

d^2 = 25+16

d^2 = 41

A = {-b + (d)^1/2}÷2a

B = {-b - (d)^1/2}÷2a

is formula pe bnaiye

Answer 2

Answer:

d ^2 = b ^2 -4 a

Step-by-step explanation:

d^ 2 = 25 - 4 x 4 x (-1)

d^2 = 25 + 16

d^ 2 = 41
